你好我是相思成灾
[nĭ hăo wŏ shì xiāng sī chéng zāi]
This translates to 'Hello, I'm Struck by Longing'. In Chinese poetry and drama culture, 'longing' often represents the yearning for a lost lover or unrequited love, where the feelings are so deep they could be compared to a disaster. Here, it shows how strongly one can fall for someone.
